SMC Corporation AK6000N Pneumatic Check Valve

The SMC AK6000N Pneumatic Check Valve is a one-way flow device for industrial pneumatic systems that prevents reverse air flow from damaging equipment or reducing system efficiency. This inline threaded valve from the AK6000 Series uses a 3/4 in NPT port (N06 configuration) and supports a maximum operating pressure of 1.0 MPa, a proof pressure of 1.5 MPa, and a cracking pressure as low as 0.02 MPa, with an ambient/fluid temperature range of -5°C to 60°C. Commonly used in pneumatic automation equipment, packaging machines, conveyors, and robotic systems across manufacturing plants, it provides reliable backflow prevention to maintain stable circuit performance and is suitable for maintenance teams, OEMs, and system integrators. Common replacements include SMC AK6000-06, AK6000-F06, and AK6000-N06.
